Oil Change

[YukonJoe619]

I have an 08 Yukon that i bought in December 08. I still haven't done my first oil change. My questions is should i go with the oil indicator, which is in 41% now or should i take in to the dealer ASAP.
Thanks
Jo

Go with the indicator until it in the 10% or lower area, then you can change it.
I use 5W-30 Extended Perf. Mobil 1 Synthetic oil with a K&N Gold oil filter every time.

 

[YukonJoe619]

Thanks. I will keep that in mind.

I 2nd the mobil 1 extended Perf. syn. oil but i use the matching oil filter. don't kno if its just me but since driving my trucc again it seems kind of revvy...dont kno i notice revs a lil past 3k from dead stops sumtimes (not accelerating fast either)

I change my oil every 3k, but that is just my opinion.

I never go by the oil indicator. I go between every 3,000 - 5,000 miles with Mobil 1 advanced fuel economy and Mobil 1 filter.

Oil will break down over time...if it's been 7-8 months since the last change it might be best to change it now. Better safe than sorry.

Taken from my manual:

Scheduled Maintenance
When the CHANGE ENGINE OIL message comes on, it
means that service is required for your vehicle. Have
your vehicle serviced as soon as possible within the next
600 miles (1 000 km). It is possible that, if you are
driving under the best conditions, the engine oil
life system may not indicate that vehicle service is
necessary for over a year. However, your engine oil and
filter must be changed at least once a year and at
this time the system must be reset. Your GM
Goodwrench® dealer has GM-trained service technicians
who will perform this work using genuine GM parts
and reset the system.
If the engine oil life system is ever reset accidentally,
you must service your vehicle within 3,000 miles
(5 000 km) since your last service. Remember to reset
the oil life system whenever the oil is changed. See
Engine Oil Life System on page 5-18 for information on
the Engine Oil Life System and resetting the system.
When the CHANGE ENGINE OIL message appears,
certain services, checks, and inspections are required.
Required services are described in the following for
“Maintenance I” and “Maintenance II.” Generally,
it is recommended that your first service be
Maintenance I, your second service be Maintenance II,
and that you alternate Maintenance I and Maintenance II
thereafter. However, in some cases, Maintenance II
may be required more often.
Maintenance I — Use Maintenance I if the CHANGE
ENGINE OIL message comes on within 10 months since
the vehicle was purchased or Maintenance II was
performed.
Maintenance II — Use Maintenance II if the previous
service performed was Maintenance I. Always use
Maintenance II whenever the message comes on
10 months or more since the last service or if the
message has not come on at all for one year.

I'll second the 3-4K oil change. Call it an old habit. The indicator light for me is useless. I tried the synthetic Mobil oil change thinking I would go further, but on inspection of the oil at 3K, I found it black. I went back to dino juice and change at 3K. When I drain the oil, it's normally only a dirty brown. No changes in mpg between the two. Just FYI.

I use 5W-30 Mobil 1 Synthetic oil also. I usually reset the oil life indicator and change on the second time around. 6-7k miles as long as the oil looks good which it has. I know it's opinion but my first oil change was @ 1200 miles.

 

[YukonJoe619]

Appriciate all the good feedback. I did call my dealer about my oil change and they did recommend that once the oil life reaches 35-40% the maintenance light should come on and they do work. But, i will go with mobil 1 synthetic oil and filter. Thanks again.

I believe the oil change indicator is fairly accurate, and you can believe what it says, however I still change mine every 3000 miles as well. By the way, if anybody is interested in extending their oil life, there is a company called Blackstone Laboratories, and they do oil analysis and they can tell you how much life is still left in your oil so you can maximize the life of your oil and save alittle dough!!. Not very expensive to do either. You can find them on the web. I send them samples periodically on my Chevy Duramax just to check up on the internals of my engine.. They can tell you alot about your engine just by doing and oil analysis.

I used to change mine every 3k miles. But now I use Mobil 1 and change every 6k.

 

[jomulk56]

I go 3,500-5,000 between changes.

 

[Harry Seaward]

I get about 9,500 miles before my oil life is down to 10%. I use Mobil 1 Truck and SUV (actually relabeled Mobil 1 Delvac), and squeeze every mile I can out of it. My '07 has about 59,000 miles on her.

 

[G35 2007]

6000 miles until a change it? that to me is CRAZY, no matter what kind of I oil you use. I always change it at 3000, I use mobil one and moblie one filter.

Oil change frequencies are one of those things that start Hatfiled/McCoy fueds.

When I was racing my 'Cuda I changed my oil every week....
My daily drivers got changes every 3K for a very long time.....
The computer in our trucks is accurate and can be faithfully relied on. But old habits die hard. So,,,,, I use Mobil 1 and instead of waiting for 20K I change it at about 6-8K when the computer tells me to. It's a great compromise.

Do what makes you feel good about your truck. You don't have to change at 3K but if you want to, cool.

 

[LVyukyuk]

I'm also trending toward 6mos before 3K comes up. So, based on towing a boat and 115 degrees during summer months, I change at 3K. I stopped using synthectic as the Yukon is not a race car. Woke me up when the Lexus reccomends AGAINST synthetic in a high compression, high octane, V6. I'd say you would be fine following the indicator, but for me, I cant rely on a computer

Corvettes have been factory filled w/ Mobil 1 since early 90s. A GM engr on another forum stated that changing at the 50% mark for mineral oil and 0% for full synthetic was OK.

 

[R.Beezy]

i dont even go by the oil life indicator. i just change the oil once a year or every 6000 miles, whichever comes first. i use royal purple oil and a mobil 1 oil filter..

 

[snowjay]

I switched to Mobil1 years ago (mid 90's) and that is all I have used in my vehicles since. On my Dodge I used to change at 6k intervals (w/K&N Filters). On my Toyota I used to change (within a week or two) of when the maint light came on which would happen every 5k (with Toyota filters). With the Tahoe I'll probably go with the indicator or 6k whichever comes first will probably use a K&N filter.

For those paranoid about extending their change intervals. Check out Amsoil. Under normal usage they recommend 25k changes. I have a friend who is a dealer and he swears by it and uses it in all his vehicles. They have some pretty nice filters as well.
